CASEMENT-ADJUSTER.

Specification of Letters Patent. Patentedlllyl-g, 1915.

Application filed March 18, 1915. Serial No. 15,360. p j

To all whom it may concern Be it known that we, VVILLIAM L. Fos'rnn and Haney J. l/VILLIAMS, citizens of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Casement-Adj usters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to casement adjusters. V

The object of the invention is to provide a device of this kind which will be practically concealed, thereby avoiding all unsightly attachments or projections from the window sash sill or frame; which will not require any special sash or frame construction; which will not interfere with screens or blinds; which will be of a strong, durable character and the locking mechanism of which will be such as to make it practically impossible to injure the device by attempts to move the sash when the device is locked; which can be adapted to right or left swing for use either with an inwardly swinging or an outwardly swinging sash; and which can be quickly and easily applied to the window.

In the accompanying drawings, Figure 1 is a perspective view of a window frame and sash equipped with our invention; Fig. 2 is a vertical, sectional view taken through the sill and the lower portion of the sash of such a window; Fig. 3 is a horizontal, sectional view taken through the adjuster on the line 00 a: of Fig. 2; Fig. 4: is a horizontal, sectional view taken through the adjuster on the line y of Fig. and Fig. 5 is a vertieal section taken through the sill and the lower part of the sash showing the adjuster applied to an inwardly swinging sash.

In these drawings we have illustrated one embodiment of our invention and have shown the same as applied to a hinged window sash mounted in an ordinary window frame but it will be understood that the inventien'is not limited in its utility to swinging windows but that it may beutilized for controlling the adjustment of any hinged member relatively to a fixed supporting member.

In Figs. 1 and 2 we have shown the window frame, at 1, as having hinged thereto an outwardly swinging sash 2 of ordinary construction. The window frame includes the usual inner sill 3 and outer sill i and it will be understood that these parts may be of any suitable construction. vRigidly secured to the frame and preferably let into the outer sill i is a guide 5 Y which is here shown as a plate provided with an elongated slot. This plate extends lengthwise of the sill and the sill is preferably cut away beneath the guide slot to'form a groove 6. Mounted .on the sash, and preferably let into the lower rail thereof, is .a looking device, which, in the form here shown,

comprises a plate 7 having secured to the inner face thereof and, in the present instance, formed integral therewith, asocket 8 which forms a vertical hearing. The socket is preferably mounted in a recess9 formed in the sash rail, whilethe plate bears against the outer face of the rail and is secured thereto by screws or in any other suitable manner. Mounted inthe bearing or socket 8 is a pivot pin or stud 10 having rigidly secured to the lower end thereof one end of an arm 11, the opposite end of which is provided with a stud 12 extending through the slot inqthe guide plate 5 and having a head 13 which lies in the groove 6 beneath the guide plate and serves to retain length of the arm, in a well known manner. 1

The bottom of the lower sash rail is cut away, as show-n at 14, to provide a recess to receive the arm 11 when the sash is moved to its closed position, at which time the arm 11, the guide plate 5 and the lower sash rail are arranged substantially parallel one to the other, as shown in 2. It will be apparent that as the sash is swung on its hinges the arm will move about its pivotal mounting in the sash railuand that the stud 12 of the arm will be guided in a fixed line along the outer sill of the window frame by the guide plate 5 with which it cooperates. i

To hold thesash in any given position we have provided means for locking the stud 8 against pivotal movement its bearing,

thereby holding the arm 11 in zfixed relation to the sash, causing the arm to extend at an .angle to. the guide slot and thus :lockingthe sash against movement. While this locking .of the pivot pin may be accomplished in .dif- Y ferent ways that here illustrated has proven very efficient in operation. In the present device the socket or vertical bearing 8 is in the form of a split sleeve, the side wall of the bearing being slotted throughout its length, as indicated at 15. Secured to the outer portion of the sleeve is a lug 16 into which is screw-threaded a stem 17 which projects through the face plate 7 of the structure and is provided on its outer end with a milled head 18, by means of which it may be rotated. The hub of this head 18 bears against the face plate and serves to limit the inward movement of the stem. Consequently, when the head is rotated to screw the stem into the lug 16 this lug and that portion of the split sleeve to which it 1s attached are drawn toward the face plate, thereby contracting the bearing opening within the sleeve and exerting a powerful clamping action upon the pivot pin. This clamping action is such as to effectually hold the arm against movement relatively to the sash, and further is of such a character that no injury can be done if pressure is applied to the edge of the sash in an effort to move the same while the pivot pin is locked against movement. If the pressure is sufficient to overcome the frictional contact between the pins and the walls of the socket the arm will yield, but the arrangement of the parts is such that this pressure would throw but little strain upon any part of the device which is liable to be strained or broken. Consequently, the device is in this respect fool proof.

The device is readily adaptable for use with either an inwardly swinging sash or an outwardly swinging sash. In Figs. 1 and 2 the sash swings outwardly and the inner portion of the bottom sash rail is cut away, thus exposing the edge of the arm 11 when it lies within the recess. hen the sash is in its closed position this recess is concealed by the inner sill 3 against the edge of which the sash rail bears. It will be noted that in this arrangement of the device the end of the pivot'pin 10 which is connected-with the arm 11 projects beyond the lower end of the socket S and the lower edge of the face plate 7 is substantially flush with the upper edge of the recess 14: in the sash rail, this being necessary to permit the movement of the arm across the plane of the face plate 7.

In Fig. 5 we have shown the device as applied to an inwardly swinging sash. Here the pivot pin has its lower end substantially flush with the lower end of the socket and the arm 11 lies back of and is concealed by the face plate 7 Because the arm moves across the outer edge of the sash rail instead of the inner edge thereof it is not necessary to cut away or recess the sash rail on its in-' ner side. Consequently, the arm is not ex posed and the only portion of the fixture visible from the inside of the window is the face plate 7 and the locking knob 18. The operation here is exactly the same as that described in connection with the outwardly swinging sash.

To permit of the same fixture being used with either an inwardly or outwardly swinging sash means are provided for securing the pivot pin in either one of two positions. To this end it is provided with two circumferential grooves 19 spaced one above the other and the socket or bearing block is provided with a recess 20 which intersects the bearing and is adapted to receive a pin 21, the outer portion of which is screwthreaded, as shown at 22, to enable it to be screwed into the opening 20. Before the pin can be inserted the pivot pin 10 must be moved into such a position as to bring one of the grooves 19 into alinement with the opening 20. The pin then extends through a porti on of that groove 19 which is in alinement with the opening 20 and thereby locks the pivot pin against axial. movement without interfering with its rotary movement. By arranging the pivot pin so that the lower groove 19 will receive the pin 21 the lower end of the pivot pin is held flush with the lower end of the socket, as shown in Fig. W hen the pivot pin is arranged to permit the pin 91 to enter the upper groove 19 the lower end of the pivot pin projects below the lower end of the socket, as shown in Fig. 2. This adjustment is a very simple one and can be ouickly and easily made and it is the only change that it is necessary to make in the device to change it from an adjuster for an inwardly swinging sash to an adjuster for an outwardly swinging sash. The only other change is in connection with the installation of the device. In the case of the inwardly swinging sash the recess to receive the arm 11 must be formed in the outer edge of the sash rail instead of the inner edge thereof. The face plate 7 and the bearing socket S are mounted on the inner side of the sash rail in both instances.

The operation of the device will be readily understood from the foregoing description and it will be apparent that we have provided an adjusting device of this kind which. is not only applicable to hinged. window sash but to hinged members of various kinds regardless of the direction in which they swing; which is very simple and very strong in its construction; and which has a power ful locking action which will effectually hold the sash in its adjusted positions.

While we have shown and described one embodiment of the invention it will be understood that this has been chosen for the purposes of illustration. only, and that we do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art. For example, while the guide plate rigidly secured to and extending lengthwise of the sill, has important advantages over any other form of connection with which we are now familiar, it is not essential to an embodiment of the invention. Any suitable device for movably connecting the end of the arm with the window frame and for guiding the arm in its movements may be substituted for the guide plate and more or less satisfactory results secured.
